loopback sample problem

[Grigori Khmyrov]

Hi all, 

I'm new user of RTEMS. I just installed it first time. I'm trying to run 
sample programs from
/opt/build-rtems/i386-rtems/pc386/samples
It seems to me that the loopback.exe program doesn't work properly on the target computer:
HSB-657I
VIA C3 Eden CPU (i386 compatible processor)
Half-Size CPU Card
With LCD, Ethernet, PC/104 &
CompactFlash, USB

I load the sample using network and GRUB utility.

The loopback.exe output looks like:
========================================================================
"Network" initializing!
"Network" initialized!
Try running client with no server present.
Should fail with `connection refused'.
Connect to server.
Can't connect to server: Connection refused
Client closing connection.

Start server.

Try running client with server present.
Connect to server.
Can't connect to server: Connection refused
Client closing connection.
Client task terminating.
========================================================================
That's it.
I've tried loopback.exe from all BSP pc386, pc486, pc586, pc686, pck6.
All of them give me the same output.
Why is it? Any help appreciated.
I compiled rtems with options
/usr/local/src/rtems-4.6.2/configure --target=i386-rtems --disable-posix 
--disable-itron --enable-tests --prefix=/opt/rtems-4.6

Thank you,
Grigori
